Question 110

The HPE AOS-CX switching case is: A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology.
  2. A routed path test confirms intended gateway ownership, bidirectional prefixes and recovery after an uplink outage.
  3. Map VLAN IDs, switchport tagging, Layer 3 gateways and traffic-policy boundaries to actual user and device populations.
  4. Failure testing verifies expected root, forwarding paths and reachability with one access or distribution component unavailable.
  5. Design link aggregation with compatible member speed, LACP state, switch support and upstream logical-system boundaries.

Explanation

Correct Answers

A:

The targeted correction for A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links is: Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology. It reduces the risk that mismatched MST regions and unintended root placement may block the wrong links and prolong convergence.

D:

A separate operational validation for A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links is: Failure testing verifies expected root, forwarding paths and reachability with one access or distribution component unavailable. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

B:

This alternative concerns inter-vlan routing and default gateway placement; its associated risk is: Placing IP gateways on the wrong layer can lead to asymmetric paths, duplicate addresses or traffic hairpinning. The observed case A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links requires the more specific mstp root and vsx edge redundancy plan control. The targeted action is: Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology.

C:

This alternative concerns vlan and subnet segmentation design; its associated risk is: A reused VLAN ID or unplanned trunk allowance can bridge separated device classes or silently block a required service. The observed case A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links requires the more specific mstp root and vsx edge redundancy plan control. The targeted action is: Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology.

E:

This alternative concerns lacp bandwidth and uplink resiliency planning; its associated risk is: A multi-chassis bundle planned without a supported peer technology can fail to aggregate or loop after partial failures. The observed case A dual-homed server is attached across VSX peers but the design treats the interfaces as two independent nonaggregated links requires the more specific mstp root and vsx edge redundancy plan control. The targeted action is: Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology.

Question 111

An HPE Aruba Networking engineer observes: A rollout disables spanning tree on a bridged campus without validating a supported loop-safe alternative.
